48 V 22 W server fan for 120 mm mounts

The 4118 model operates on a 48 V DC supply and draws 22 W. Its square frame measures 120 mm on each side with a 38 mm thickness. A four-wire connection provides speed control and monitoring for server and industrial chassis.

Four-wire interface enables PWM regulation

The extra conductors allow the host system to adjust fan speed dynamically and read back actual RPM. This reduces acoustic noise during low-load periods while maintaining full airflow when components demand maximum cooling.

Questions about this item

What maintenance or replacement will the 4-wire fan need later?

The 4-wire server fan uses ball bearings that eventually wear out; plan to replace the unit when noise or vibration increases beyond acceptable levels.

What limit shows up first under sustained use at 22W?

Continuous 22W draw at 48V makes bearing temperature the first limit; monitor chassis airflow to keep the 120x120x38mm housing within its thermal envelope.
